Utility pedals - what are they?
First, they do not alter the characteristics of the instrument signal. Therefore, they are not “effects”.
Second, they act like “glue” to the effect pedals installed on a pedal board by providing control of signal flow through splitting, summing, routing, buffering, and interacting with effect operation..
Okay? More words, please.
One of the recent trends is to run parallel effects instead of serially. This can be easily done by splitting the instrument signal, applying those “splits” to separate effects, and then combining (summing) those effect outputs back together. The individual effect characteristics can be adjusted to taste without undue interaction with the other effects.
Real-World Example
See below a possible Utility Pedal scenario:
Description
The instrument signal enters the buffer.
